Angling for evolutionary answers: The work of David O. ConoverHuman activity has certainly affected our physical environment - but it is also changing the course of evolution. This research profile follows scientist David O. Conover as he investigates the impact of our fishing practices on fish evolution and discovers what happened to the big ones that got away.

A closer look at a classic ring species: The work of Tom DevittThe Ensatina salamander has been extensively investigated because it is a ring species — a species that demonstrates how geography and the gradual accumulation of genetic differences factor into the process of speciation. Biologist Tom Devitt continues the more than 50 years of Ensatina research by applying new genetic techniques and asking new questions about this classic evolutionary example.

How to survive a mass extinction: The work of David JablonskiThrough detailed analysis of patterns in the fossil record, scientist David Jablonski reconstructs the rules that helped dictate who lived and died in past mass extinctions. This research profile describes his surprising discoveries and their disturbing implications for the biodiversity crisis today.

Biological warfare and the coevolutionary arms raceThe rough-skinned newt looks harmless enough but is, in fact, packed full of one of the most potent neurotoxins known to man. Find out how an evolutionary arms race has pushed these mild-mannered critters to the extremes of toxicity and how evolutionary biologists have unraveled their fascinating story.

How are humans related to other primates? In this two-part laboratory students analyze skull morphology and DNA sequences among primate species to answer one of the most meaningful questions in biology: How are humans related to other animals?

Journal Club ToolkitThis set of teaching materials aims to help instructors engage their students with the primary literature in evolutionary biology through a "journal club" that can be implemented in a discussion section or smaller class. It includes several helpful tools: annotated articles, a reading guide, additional suggested reading, and tips for students leading a discussion of a journal article.
